As owner of the Arts Factory and Bar+Bistro, Wes Myles has obtained a litany of permits and licenses over the years. It’s part of running a business. But the Southern Nevada Health District’s requirement that he have a state Producer’s Certificate for the small herb garden on his patio was a bit confusing, considering that the planter has only four small rosemary bushes, one basil plant and one sage. It’s hardly the large crop or farm referred to on the application. Turns out, business owners can’t just plunk anything into the ground and serve it to customers. Food establishments growing plants for commercial use must have this $50 certificate obtained through the Nevada Department of Agriculture. The state does not require the certificate, but the Health District does, though it couldn’t say how many restaurants have one.
